Equitable Tolling in California: The Three Requirements and How It Works

Equitable tolling in California is a court-made rule that pauses the statute of limitations when a plaintiff has been diligently pursuing a legal remedy through the wrong forum or through a required administrative process. It exists so that a good-faith litigant doesn’t lose their case on a technicality after doing everything a reasonable person would do. A judge decides whether to apply it, and the plaintiff carries the burden of proving they deserve the pause.

The doctrine traces to the California Supreme Court’s 1978 decision in Addison v. State of California, which set the three-part test courts still use. It comes up most often when someone files a claim in a court that lacks jurisdiction, or when they spend time exhausting an administrative remedy before suing.

The Three Requirements a Plaintiff Must Prove

To get the clock paused, you have to show three things: the defendant received timely notice of the claim, the defendant won’t be prejudiced by the delay, and you acted reasonably and in good faith.1Supreme Court of California. Saint Francis Memorial Hospital v. State Department of Public Health Later decisions, particularly McDonald v. Antelope Valley Community College District, spelled out what each element requires in practice.2Stanford Law – Supreme Court of California. McDonald v. Antelope Valley Comm. College

Timely Notice to the Defendant

The defendant in the later lawsuit must have learned about the plaintiff’s claim within the original limitations period. In most cases that means the plaintiff filed the first action, whether in the wrong forum or through an administrative agency, before the original deadline ran. That first filing has to alert the defendant to the underlying facts so they know to start investigating. Usually the defendant in both proceedings is the same party, though courts have found this element met even when it isn’t, as long as the defendant knew the relevant facts.3Justia. CACI No. 457 – Statute of Limitations – Equitable Tolling – Other Prior Proceeding

No Prejudice to the Defendant

The delay caused by the first proceeding cannot leave the defendant worse off in defending the second. Courts look at whether evidence was lost, whether witnesses became unavailable, and whether the passage of time made the defense materially harder. This element is often satisfied almost by default when timely notice exists, because a defendant who knew about the claim early had every chance to preserve evidence. The core question is whether tolling would prevent the defendant from mounting a fair defense on the merits.1Supreme Court of California. Saint Francis Memorial Hospital v. State Department of Public Health

Reasonable and Good-Faith Conduct

This is where most equitable tolling arguments succeed or fail. The plaintiff’s conduct is evaluated on two levels. It must be objectively reasonable, meaning fair and sensible given the circumstances. And it must be subjectively in good faith, meaning the delay resulted from an honest mistake rather than a strategic move.1Supreme Court of California. Saint Francis Memorial Hospital v. State Department of Public Health A plaintiff who filed in the wrong court because of a genuine jurisdictional question looks very different from one who voluntarily dismissed a case for tactical reasons. Courts also stress that once the first proceeding ends, the plaintiff must file the second action quickly. Waiting months without explanation after the tolling event ends will sink a claim.

When California Courts Apply Equitable Tolling

Equitable tolling is not a safety net for anyone who misses a deadline. California courts apply it in a fairly narrow set of recurring fact patterns, all involving a plaintiff who chose one available legal path before switching to another.

Filing in a Court That Lacks Jurisdiction

The textbook example is a plaintiff who timely files a state-law claim in federal court and then has it dismissed because the federal court lacks jurisdiction. The limitations period for refiling in state court is tolled for the entire time the federal action was pending, provided the three requirements are met. The key is that the initial filing was a reasonable choice. If a jurisdictional question was genuinely uncertain, the court will treat the federal filing as evidence of diligence rather than negligence.3Justia. CACI No. 457 – Statute of Limitations – Equitable Tolling – Other Prior Proceeding

Exhausting an Administrative Remedy

Many California claims require the plaintiff to go through an administrative process before suing. FEHA discrimination and harassment claims are the prime example. A plaintiff must first file a complaint with the Civil Rights Department (formerly the Department of Fair Employment and Housing) and can only sue after receiving a right-to-sue notice. The one-year deadline to file suit runs from the date of that notice. When the EEOC and the state agency are both investigating the same charge, the FEHA statute of limitations is tolled while the federal investigation plays out.4California Legislative Information. California Government Code 12965

Workers’ compensation claims present another common scenario. A worker pursuing a comp claim for a workplace injury may also have a civil personal injury claim against a third party based on the same facts. Time spent pursuing workers’ compensation can toll the limitations period for that related civil action, because the two proceedings involve overlapping facts and the defendant is on notice of the underlying injury.

Voluntary Dismissal Won’t Get You There

Courts draw a sharp line between a plaintiff forced out of one forum, such as by a jurisdictional dismissal, and a plaintiff who voluntarily leaves. A California Court of Appeal rejected equitable tolling where a plaintiff voluntarily dismissed a state court case, tried to move to federal court, failed, and then attempted to return to state court after the limitations period had passed. The court found that a strategic, voluntary dismissal was neither reasonable nor in good faith. Forum-shopping is exactly the behavior the doctrine was never designed to protect.

How the Paused Clock Works

Equitable tolling pauses the limitations clock; it does not reset it. Whatever time remained when the plaintiff began the first proceeding is the same amount of time available after that proceeding ends. If you had 90 days left on a two-year deadline when you filed an administrative complaint, you get exactly 90 days to file your civil lawsuit once the administrative process concludes. The clock does not restart at two years, and you do not get extra time beyond what you originally had remaining.

This math matters. Plaintiffs who wait until the last weeks of a limitations period to pursue an administrative remedy leave themselves an extremely tight window once the process finishes. Keep a precise record of when the original deadline started running, when the first proceeding was filed, and when it ended. That timeline is what your remaining window is calculated from.

Equitable Tolling Is Not Equitable Estoppel

These two doctrines sound similar and get confused constantly, but they work in opposite directions. Equitable tolling focuses on the plaintiff’s conduct: did they act diligently and in good faith while pursuing another remedy? The defendant’s behavior is irrelevant. Equitable estoppel focuses on the defendant’s misconduct. It prevents a defendant from using an expired statute of limitations as a shield when the defendant’s own wrongdoing caused the plaintiff to miss the deadline.3Justia. CACI No. 457 – Statute of Limitations – Equitable Tolling – Other Prior Proceeding

The California Supreme Court drew the distinction in Lantzy v. Centex Homes: tolling deals with when the limitations period runs and when it can be suspended, while estoppel kicks in only after the period has already expired. Estoppel bars a defendant from raising the deadline as a defense because the defendant’s own actions induced the plaintiff to delay. If your employer lied to you about resolving your complaint internally and that caused you to miss the deadline, that is an estoppel argument. If you filed a timely workers’ compensation claim and are now switching to a civil lawsuit based on the same injury, that is a tolling argument.

Statutes of Repose Are a Hard Stop

Equitable tolling generally cannot extend a statute of repose. A statute of limitations starts running when you discover (or should have discovered) your injury. A statute of repose starts running from a fixed event regardless of when you learn about your claim, and it sets an absolute outer boundary on liability. California’s ten-year construction defect statute of repose is a prominent example: no action for a latent deficiency in design or construction can be brought more than ten years after substantial completion of the improvement, regardless of when the defect is discovered.5California Legislative Information. California Code of Civil Procedure 337.15

Repose statutes exist specifically to give defendants a guaranteed end date for potential liability, and allowing equitable exceptions would undermine that purpose. If your claim is governed by a statute of repose rather than a standard limitations period, equitable tolling will almost certainly not save a late filing.
